Vast Resources to leverage new equipment and XRT ore sorting at Baita Plai

Vast Resources has devised a new mechanised mine plan for its Baita Plai polymetallic mine in Romania that will see mining capacity increase by 65% and ore sorting employed to increase mill feed grades.

The new mine plan includes the acquisition of three LHDs (including at least one narrow-vein electric LHD), an Aramine face jumbo drill rig, two Resemin Muki 22 long hole drilling rigs and a TOMRA X-ray Transmission (XRT) ore sorter.

Execution risk is expected to be significantly reduced compared with the old labour-intensive plan through the employment of senior international staff; the use of increased mechanisation; and the fact that shortly, with the expediated development plan now possible through the new equipment, the mining areas will be in areas newly drilled by the company and not in less stable old mining areas, the company said.

The company, in co-operation with TOMRA Mining, has concluded an initial investigation on ore from Baita Plai as part of the development of the new mining and processing plan. The objective of the work was to determine the amenability of ore from Baita Plai to be pre-concentrated using TOMRA sensor-based sorting technologies to produce a high-grade pre-concentrate, pre-milling feed.

“The study showed a clear amenability for the ore to be separated using TOMRA’s advanced XRT technology to identify both massive mineralisations, as well as fine mineral inclusions, using its proprietary combination detection algorithms to produce a high-grade pre-concentrate and eliminate non-grade containing waste material,” the company said.

The XRT implementation and processing plant upgrades are set to be completed by December 2021, the company said, with mill feed grades expected to be concentrated by 1.25-1.75 times. This would see the sensor-based sorter shift 60% of tonnage into the accept stream for the mill and 40% into the reject stream, with a 92% yield in the accept tonnage.

The new mine plan presents a cost reduction of 21% in dollars per mined tonne with an operational efficiency of 63 tonnes per total employee costed (TEC) at steady state, versus the previous plan efficiency metric of 43 tonnes per TEC, Vast Resources said. It also sees mining capacity rise to 22,000 t/mth, from 13,300 t/mth.

Andrew Prelea, Chief Executive Officer of Vast Resources, said: “This is a robust and comprehensive mine plan which has been developed using rigorous technical parameters. On behalf of the board, I believe the plan set out to shareholders today represents a benchmark for us to deliver on over the coming years in tandem with our broader expansion plans at Baita Plai and across our wider portfolio.”

Astec Industries looks to boost Africa and Middle East business with Aramine tie-up

Astec Industries, through its newly organised Africa and Middle East (AME) business unit, has announced a distribution partnership with France-based mining and underground solutions specialist Aramine.

This strategic alliance will enhance the supply, distribution and service of Astec mining, quarrying and materials handling equipment in numerous African countries, Astec said. This includes rock breaker systems, rock crushers, feeders, vibrating screens, conveyors, washing and classifying equipment for open-pit mines, alongside underground mining products and bulk material handling systems.

Aramine has been appointed as a dealer for Astec Material Solutions products in Mauritania, Mali, Senegal, Guinea, Ivory Coast, Burkina Faso, Benin, Togo, and Niger in West Africa, as well as in Algeria, Tunisia and Morocco in the Maghreb region.

Vinesh Surajlall, Director – Material Solutions at Astec AME (pictured), said: “The expansion of the Astec portfolio that will be distributed by Aramine is an important evolution in our commercial relations, as we collaborate in very active and demanding markets in West Africa and the Maghreb.

“With this partnership, we are developing a new customer proximity offer, combining expertise, services and quality products.”

Jaime Martel, Key Regional and Product Manager and Head of Distribution Partnerships at Aramine, says the new venture represents Astec’s confidence in Aramine. The two organisations have enjoyed a longstanding distribution partnership which previously encompassed only the BTI range of rock breaker and boom systems.

“The extension of our alliance, to cover the material solutions offering, will equip us further in meeting the needs of our customers in the regions,” he noted.

In addition to its recognised expertise and technical service, Aramine will leverage its networks of subsidiaries and partners in the regions, Astec said.

The recent group restructuring and the establishment of Astec Industries AME will deliver further benefits for Astec customers in the region, the company says.

“The move forms part of Astec Industries’ international expansion strategy, with regional sales organisations established to improve customer interaction and support for the complete range of Astec products,” Astec said. “Astec Industries AME is one of these regional sales organisations and will be responsible for business relationships in Africa, the Middle East and Central Asia. The AME offices are based in Elandsfontein, Johannesburg, with regional sales managers positioned strategically within the region to support the business’s dealer network and customers.”

Surajlall concluded: “We look forward to contributing to the continued growth of our customers’ businesses through this enhanced structure, optimised product range and support structures throughout the Astec Industries organisations. This expanded partnership with Aramine represents an important opportunity to strengthen the presence of Astec Industries Inc in these significant territories.”

ARMZ, Aramine partnership brings battery-powered narrow vein LHD to Russia

ARMZ Mining Machinery says it has become the first and only company in Russia and the CIS producing lithium-ion battery-powered mining equipment through a collaboration with Aramine.

The company, part of ARMZ Uranium Holding Co, has started producing the mining equipment in Krasnokamensk, in the Trans-Baikal Territory of Russia, at the site of Priargunsky Industrial Mining and Chemical Union (PIMCU, PJSC is a part of ARMZ Uranium Holding Co).

The project is being implemented under an industrial partnership agreement ARMZ Uranium Holding Co and France-based Aramine, signed in April 2019. As part of this pact, ARMZ Mining Machinery is the project operator.

ARMZ said the production from Krasnokamensk will cover the internal needs of ROSATOM State Atomic Energy Corp (of which ARMZ is a part of), and let the company enter foreign markets with competitive products.

The ARGO LHD 140B is designed specifically for underground work in narrow-vein deposits, according to ARMZ. Based off the design of the Aramine miniLoader L140B, it has a width of 1.1 m and a bucket carrying capacity of 1.3 t. A 50 kW engine and a lithium-ion battery pack provide high mobility and continuous operation for up to four hours; at the same time, offering low noise, minimal heat transfer and no gas contamination in the mine. The machine significantly outperforms the requirements of the Russian standards in industrial safety, according to ARMZ.

Ivan Kiselev, Director General of PIMCU, PJSC, said: “New LHD machines will let us efficiently and reliably carry out operations for the loading and transportation of ore inside the stopes. The transition to a new battery-powered narrow-vein equipment is an economically viable solution aimed at reducing operating costs and improving the quality of ore mining.”

Igor Semenov, Executive Director of ARMZ Mining Machinery, said the production of the ARGO LHD 140B means ARMZ Mining Machinery has become the first and only company in Russia and the CIS producing lithium-ion battery-powered mining equipment.

He explained: “We adapted the Aramine design and specifications to Russia standards, organised the technological process: in-house production of the structural frame, arms and dippers, assembly of body parts, installation of components, start-up and commissioning of machines. Our next step will be the localisation of the production of lithium-ion batteries and the expansion of the product line with other types of underground equipment.”

The first serial vehicles have already passed factory tests, according to ARMZ, and will be sent to the uranium mines of PIMCU, PJSC this month. In 2021, the ARGO LHD 140B will enter the Russia market and will then gradually become available in other countries within the customs union, it said.

Aramine bolsters market capitalisation with merger

Aramine and Aramine Loaders have been absorbed into the company Groupe Melkonian as part of a merger that will strengthen the company’s capitalisation, it said.

Since January 1, Aramine is now a “simplified joint stock” company with a capital of €20.41 million ($22.7 million), compared with €900,000 previously, registered in the Aix-en-Provence Trade and Companies Registry, it said.

The merger’s objective is to strengthen the company’s relationship with its stakeholders and to offer a single point of contact to our partners, it said.

Groupe Melkonian is owned by Geneviève, Marc and Christophe Melkonian, the Presidents of Aramine (pictured).

Aramine and Epiroc sign mining and tunnelling distribution deal

Building on an already strong partnership, Epiroc and Aramine have signed a distribution contract that will see the France-based company become Epiroc’s official distributor of underground mining and tunnelling equipment in France and several Central and West African countries.

Aramine, which is already the official distributor of Epiroc drilling, loading and rock transport products, said: “The Epiroc product range for mines and tunnels perfectly completes the portfolio of machines dedicated to galleries of small and medium sections designed by Aramine.”

The African countries that Aramine will service include the Central African Republic, Benin, Burkina Faso, Cameroon, Chad, Congo-Brazzaville, Côte d’Ivoire, Gabon, Gambia, Guinea-Conakry, Equatorial Guinea, Liberia, Mali, Mauritania, Niger, Senegal, Sierra Leone and Togo, according to the company.

Marc Melkonian, President of Aramine, said: “Epiroc’s trust is a mark of recognition of our long-standing partnership, and this obvious collaboration between our two companies allows us to offer a wide and complete solutions range for mines and tunnels to our customers.”

Aramine is strengthening its presence in certain countries in line with the Epiroc distribution deal.

For France, Pierre Donnadieu, a specialise in underground mining and tunnelling will join as the new Regional Sales Manager, while, on the African continent, the distribution of Epiroc products is ensured by Aramine Burkina, located in Burkina Faso’s capital Ouagadougou.

Jean-Baptiste Corona, Director Epiroc France, said: “The long-term link between Aramine and Epiroc is historic regarding both our collaboration and the distribution of the products of our respective brands. It is therefore an important evolution of these relations since we work hand in hand in very active and demanding markets such as France and West Africa. We are developing a new local offer with this partnership, combining expertise, services and quality products.”

Aramine launches diesel-electric drill for narrow vein mining

Aramine has looked to complete its equipment range for narrow vein mines with the introduction of its diesel-electric hybrid miniDriller DM901 HDE drill rig.

The compact machine uses the diesel engine for tramming and electric motor for drilling, according to Aramine, while it can be operated tele-remotely, removing the operator from potential hazards.

The DM901 HDE has a low centre of gravity for optimal stability. Despite its narrow width, the two front stabilisers offer perfect drilling conditions, according to the company. This allows for both face and vertical drilling, Aramine said.

Aramine says the DM901 HDE only requires a 400 V electric connection and a water supply to operate and is designed with modular elements for easy assembly/disassembly in a mine. It “sneaks wherever our L130 and L150 miniLoaders go”, Aramine said. This means the new machine is ideal for sections between 6 sq.m and 12 sq.m.

With an existing partnership between Aramine and Epiroc, the company can offer an exclusive optional version with an Epiroc Feed and Drifter, Aramine said.

“As most of Aramine machines are, the DM901 HDE complements perfectly the Epiroc range,” Arnaud Paul, Aramine Equipment Sales Director, said.

Aramine says it is preparing its fully-electric battery-powered version for 2020, with innovations at all levels of the machine.

Aramine and ARMZ sign agreement for L140B battery-powered miniLoader

Underground vehicle specialist Aramine says it has signed a partnership agreement with Russia uranium producer, ARMZ, for the assembly of its L140B battery-powered miniLoader.

The pact was signed by ARMZ Uranium Holdings’ Director General, Vladimir Verkhovtsev, and Aramine Presidents, Marc Melkonian and Christophe Melkonian, during the 23rd International Mining World Russia Exhibition, in Moscow.

“Production of Aramine battery loaders will improve the working conditions of the miners, increase the level of safety and, of course, increase the volume of ore mining,” Verkhovtsev said.

Just a few months ago, Aramine looked to extend the continuous working time of its battery-powered miniLoader L140B by providing a battery change-out option.

This miniLoader L140B, launched in 2017, is an optimised and advanced version of the L120B, carrying more capacity – 1.3 t. While the company’s new option allows the machine to run full time without being immobilised during charging, the standard L140B offers four hours of continuous operation. This allows for the mucking of three to four faces in one shift with a simple charging system integrated into the machine and requiring a plug to the wall, according to the company.

The miniLoader does not require massive electrical installation, with the power required only being about 7 kW, compared with the 45 kW typically needed for an electric machine with cable, the company said.

ARMZ recently announced plans to reduce the level of risk both underground and above-ground at its industrial complexes, with Verkhovtsev saying the company was looking at, among other things, automation and implementation of the most modern technologies at its operations.

Aramine equips miniLoader L140B with battery change-out system

Aramine has looked to extend the continuous working time of its battery-powered miniLoader® L140B by providing a system that, it says, will “totally change the way you can use a battery machine underground”.

The standard L140B, launched in 2017, offers four hours of continuous operation. This allows for the mucking of three to four faces in one shift with a simple charging system integrated into the machine and requiring a plug to the wall, according to the company. This does not need big a electrical installation, with the power required only being about 7 kW, compared with the 45 kW typically needed for an electric machine with cable.

Now, the company has looked to offer its customers another battery change-out option.

The new optional QRS features a quick disconnect battery module, Aramine said. This feature, which has been added without increasing the length of the machine, allows the machine to run full time without being immobilised during charging, according to the company. “The system is ultra fast and smart with a W type aligning system and an auto locking device,” Aramine said.

There is a lever with a lock on the system that ensures optimal safety of the battery pack, the company added.

Aramine said its R&D department has worked hard on reorganising the components inside the machine and selecting an extremely reliable and safe connecting system with maximum power in order to retain the force of the miniLoader.

“The R&D department has also run a lot of tests to find the good angle of adherence in the W type system and find a faultless self-aligning mechanism,” the company said.

In order to benefit from the QRS features, a mine will require a battery change area with crane to change out the battery safely and easily. But, with these elements in place, the battery replacement process can take around 10 to 15 minutes, according to Aramine.

With the QRS machine, the operator can have only one machine in operation in the mine, whereas with the fix frame version of the miniLoader, the customer requires two machines for the same productivity (one charging while the other is working), Aramine said.

These new features are not only available on new machines, according to Aramine. All operating miniLoader L140Bs with a fixed frame can be converted with this new QRS system thanks to an after-market kit.

The company will showcase a battery-powered miniLoader L140B, with 1.3 t capacity, equipped with optional QRS at the Bauma fair, in Munich, Germany, from April 8-14.
